ClearOne has been awarded a new patent relating to power transmission for Power over Ethernet (PoE) systems by the US Patent and Trademark Office. Awarded on April 14, the patent describes a simple method for providing power to multiple devices in a daisy-chain series connection using PoE. Use of the new method can eliminate the 100-meter Ethernet distance constraint for power and data transmission.
ClearOne’s technology disclosed in this patent brings benefits for at least two applications. First, it is useful for devices such as audio products including microphones and speakers, security and conferencing cameras, remote sensors, smart home technologies like thermostats and alarm systems, as well as computers and displays, all of which can be freely deployed anywhere within the reach of an Ethernet cable.
Second, the patented technology is also useful for transmitting power only, without data, where access to electrical power outlets may be inconvenient or power outlet safety is a concern. For example, mobile device chargers, lighting, and other battery-powered personal devices, and even toys can utilize this technology throughout the work or home environment because the patented method supplies power whether data is present or not.
Another benefit of this application is the elimination of redundant electrical wiring and outlets to distribute power by using existing and common Ethernet cabling.
US patent number 10,620,678 entitled “System for Transmitting Power to a Remote PoE subsystem by forwarding PD Input Voltage” is part of ClearOne’s patent portfolio covering multiple new technologies in the fields of audio and video processing, audio and video streaming, and innovative communication technologies.
